An investigation into how the amount of light affects the rate of photosynthesis We are going to do an experiment on how the rate of photosynthesis is affected by the light intensity. The plant that will be photosynthesising is called elodea. It is a pondweed therefore photosynthesises under water. We will now be able to count the oxygen bubbles or develop a method were we can collect the oxygen given off by the pondweed. Photosynthesis is what keeps a plant alive. The energy for photosynthesis to work comes from the sun the air and the ground. A substance called chlorophyll absorbs the sunlight. Chlorophyll is found in chloroplasts and chloroplasts are mostly found in cells in the palisade layer. Also for photosynthesis to be carried out it needs water and carbon dioxide. The carbon dioxide is dissolved into the water and the pondweed will get water and carbon dioxide through diffusion....
